IMPROVEMENT IN SEWING-MACHINE BINDERS.

Specification formingpart of Letters Patent No. 180,177, dated July 25,1876; application filed November 6, 1875. 4

To all whom it may concern:-

Be it known that I, JOHN VAN LEUNEN, of Oovington, in the county ofKenton and State of Kentucky, have invented a new and useful BinderAttachment for Sewing-Machines, of which the following is aspecification:

My invention relates to a binder which is capable of being used upon anysewing-machine, and of being readily adjusted to suit variousthicknesses of fabrics and Widths of binding Without detaching theimplement from the cloth-plate, said adjustment-s being easily effectedby manipulating a couple of set-screws and a regulating-cam, ashereinafter more fully explained. Furthermore, the binder is constructedwith detachable ed ge-turners, that are capable of being adjusted atwill, and without removing the implement from the cloth-plateof thesewing machine. I

By thus rendering these devices detachable 1 am enabled to use thevarious sized edgetnrners for diftercnt thicknesses of tapes, by whicharrangement the action of the binder is rendered more easy and perfect,as there is no crowding of the goods in attempting to feed a heavyfabric through a comparatively contracted space. This act of adjusting,or of detaching, or of applying the edge-turners, is accomplished in afew moments by means of two set-screws, as will presently appear.

In the accompanying drawing, Figure 1 is a .perspective view of mybinder, attached to the cloth-plate of asewing-machine, the implementbeing set .to bind a narrow tape upon a thin piece of goods. Fig. 2 is ahorizontal section of the binder detached from the clothplate, thesection being taken at the line 1 1 of Fig. 2. Fig. 3 is a verticalsection through the binder at the line 2 201 Fig. 3. Fig. 4 is anothervertical section at the line3 30f Fig. 2. Fig. 5 is an elevation of theguidingscroll and its accessories. Fig. 6 is a perspec' tive view of theregulating-cam detached from the binder. Fig. 7 is a vertical section,showing the manner of binding a broad tape upon a thick piece of goods.Fig. 8 is a plan of that form of my binder in which the adjustable anddetachable edge-turners are employed. Fig. 9 is a section at the line 4.40f Fig.8, the upper edge-turner being shown shifted toward theregulatingcam. Fig. 10 is a section at the line 5 5 of Fig. 8. Fig. 11is a section at the line 6 6 of Fig. 8. Fig. 12 is a perspec-' tiveview, showing a portion of the bed-plate of the binder, with the twoedge-turners detached therefrom. Fig. 13 is a perspective view of twoedge-burners adapted for use with a thicker piece of tape. Fig. 14. is aperspective view of two edge-turners of still greater capacity,the'upper one being shown as adjusted outwardly from the lower one.

The supporting member of my binder consists of a flat metallic plate, A,provided with one ormore slots, a, for the reception of a setscrew, B,wherewith the binder is secured to the cloth-plate O of anysewing-machine, and

in such manner as to bring the needlecin close proximity to thedelivering ends of the edge-turners, that will be presently described.

Resting upon the bed-plate A, and capable of being adjusted at will, isa frame, consisting of two parallel bars, 1?. and F, of which the one Eis the most; remote from the needle 0. The rear ends of these bars areuuitedby.

a bar, G, having a rib or flange, g, projecting from it,-said rib beingdesigned to facilitate,

the shifting of the frame E F G.

The bar E is slotted at e to receive a screw, H, that projectsvertically from the bed-plate A, and carries a thumb-nut, h. Theopposite barF is slotted at fto receive a screw, I, which to its properpath toward and from the binding-scroll whenever it is being adjusted,and,

after said frame has been properly set, it is secured in position bytightening the nut h.

The bar E has a vertical projection, E, to

which is adjustably secured, by a screw, K,

the receiving end of guiding-scroll L, which gradually tapers toward itsdelivery end, as

more clearly shown in Fig. 5. This scroll is provided with twooutwardly-projecting lips,

M N, which are benttoward each other, andthen recurved respectively at mn, so asto a guide to the edge of the fabric R, while the passage Pconducts the binding-tapes in a proper path. v

Secured at the junction of the two recurved lips, m n, is a tongue, T,which acts as a ten sion device to maintain the tape Sin its propercentral position within the scroll L; and said tongue also prevents thetape becoming wrinkled on its passage through the binder.

The lips of the scroll are slotted, respectively, at m n, to receiveblades Q Q, whose fixed ends are attached to the bed-plate A by screw a,the free ends of i said blades being furnished with inwardlyprojectingfingers q 4, that serve as guides for the edges of the tape S when itfirst enters the binder. These blades are elastic enoughto yield whenthe scroll is adjusted in either direction.

Projecting rearwardly from the delivery end of scroll L is a stud orstump, l, which traverses a slot, at, in the marginal flange u of asemicircular plate, V. This flange gradually increases in height fromright to left as it winds around the plate V, so as to form a helicalcam, and the exposed face of said cam is connected at u, to allow a freepassage of the fabric andbinding-tape.

The flanged segmental disk V is provided with a central aperture, '0,for the. reception of a pivot-bolt, W, .wherewith said disk is coupledto the circular enlargement'F of bar F. The pivot W has a non-circularshank, 10, that traverses a slot, a, in the plate A. Furthermore, thisdisk is furnished with a handle, o, wherewith said disk may be rotatedin either direction upon its pivot W. Projecting from said disk orhelical cam is a screwthreaded stem, at, which, after passing through aslot,f, inenlargement F, has a nut, X, engaged with it, which serves tomaintain said cam immovably to its adjustment. The aforesaid slotf isconcentricwith the pivot of the disk.

Y represents the upper edge-turner, its flat expansion Y projectingtoward the scroll L. This edge'turner is attachedto a spring-bar, Z, bymeans of clips 3 and rivet 3 which arrangement enables a newedge-turnerto. be applied to the binder without in any way in- "tert'ering with theattachment Z. The bar Z screw,9, which projects rigidly from the plateOisa nut, which, being engaged with the crew!) serv sto maintain theshank 8 securely in the undercut recess 7. By simply slackening the nut10, as shown in Fig. 12, the edge-turner can be detached from thebinder, and a larger or smaller one substituted in its place.

The upper edge-turner is rendered adjustableand'detachable in thefollowing manner:

Said device Y has projecting from it a stump,

11, which traverses a longitudinal slot, z, of spring-bar Z, this slotbeing long enough to allow the edge-turnerY to be shifted as far as maybe necessary for all purposes.

Rigidly secured to bar Z, and projecting upwardly therefrom, is' ascrew, 12, carrying a nut, 13, which latter, when screwed down upon theclips y,'prevents any accidental shifting of the upper edge-turner.

Byret'erring to Figs. 12, 13, and 14 it will be noticed that therespective pairs of edgeturners are of an increased capacity, the onesshown in Fig.12 being adapted for use with very thin tape, while thedevice represented in Fig. 14 is capable of operating upon the thickesttape that can be. employed with the binder.

Fig. 13 represents .a pair of edge-turners that are to be employed witha tapeof medi um thickness.

As many intermediate pairs of detachable edge-turners may be employed asmay be preferred, although three or four. different sizes will generallybe sufficient for all ordinary purposes. 2

.After having selected the proper-sized edgeturners forthe tape that isto be bound to the fabric, the lower one A has its tongue 8 inserted inthe recess 7, and then secured immovably in position with the nut 10.The clips 3 ot'the upper edge-turner Y are then slipped along the springbarZ, and the stump I1 is inserted in the slot 2'. The nut 13 is thenbrought to bear upon said clips, so asto prevent the device Y 3 beingaccidentally shifted in either direction longitudinally of thesupporting-bar Z.

The shifting of the upper edge-turner can be accomplished withoutdetaching the binder from the machine, or removing the goods from thebinder.

It is eviden'tthat a great saving of time is effected by thesuse of my.implement.

These adjusting devices being so simple and accessible, they "can bemanipulated with the utmost facility by the women who run the machine.

A nick, 14, in the lower member A enables the latter to be readilywithdrawn fronrits socket as soon as the nut 10 is unslackened.

The manner of adjusting and operating my binder is as follows: If itshould be desired to attach a narrow binding, for example,"to a thinpiece of goods, as shown in Fig. 1, the sliding frame E F Gris firstshifted so as to bring the scroll L and the adjusting devices U V Xsuflieiently nearthefront edge of the binder, afterwhich the said frameis secured by tightening the nuth. The handle 2; of disk V is then swungtoward the needle 0, which act causes the free end of the springbar Z,with its attachment Y Y, to approach the lower edge-turner A, and assoon as these devices Y, Y, and A have been brought into sufficientproximity, the nut X is screwed down so as to prevent any furtherrotation of the regulating disk or cam V. The tape S is then passedthrough the annular space P of the scroll L, with the edges of thebinding material resting against the fingers q q, and

said tape is carried forward between the tongue T and the scroll L. Theedges of the tape are now properly bent over by means of theedge-turners A Y, and the fabric R is then inserted in the channel 0formed by the recurved members m a of the scroll. The sewing-machine isnow set in motion, and, as the cloth is fed along, the tape is foldeddown smoothly and uniformly by the action of the edge-turners A Y, andsecurely stitched to the fabric B, the flat extension Y serving to laythe tape perfectly level before it enters the turner Y.

If it should be desired to operate upon thicker goods, the handle 2! isswung to the right or away from the needle so as to bring a moreelevated portion of the helical cam U to bear beneath the spring-bar Z,and consequently the distance between the edgeturners A and YY isincreased accordingly. It will thus be seen'that the space between thestitching and the curved edge of the binding is regulated by simplyshifting the sliding frame E F G toward or away from the needle, whilegreater or' less clearance between the binders A and Y Y is obtained bya proper manipulation of the handle 0.

As both of these operations can be efiected in a few minutes withoutremoving the device from the sewing-machine, my binder will be found tobe much more readily.manipulated and less liable to derangement thanthose in general use. The adjustment of the edgeturners A and Y beingwholly simultaneous, it follows that the two nuts h and X are all theappliances that require regulating, no

matter how thick or how thin the fabric is, or

how wide or narrow may be the binding.

The'scroll L M N and regulating-cam U .M

V '2; being both attached to the same sliding frameE F G, it will beunderstood that they have a simultaneous movement toward or away fromthe needle, and therefore the scroll cannot lose its proper relativedistance from the adjusting-cam.

The stud l, traversing the bisecting slot u in the helical flange of theregulating-cam, operates to maintain the tongue T and the scroll M Nprecisely in alignment with the edge-turners A Y at every adjustment ofthe latter.

What I claim as new, and desire to secure by Letters Patent, is-

1. In combination with the bed-plate A and its attached edge-turners Aand Y, the' shift able-frame E e H h F ff -I G, carrying the scroll L lO P and the regulating helical cam U u V v W X m, as and for the purposespecified.

2. The combination of scroll L M N O P, tongue T, stud l, and thehelical cam U V, provided with the slot u, as and for the objects setforth.

3. In combination-with the fixed bed plate A and its Y attached blades Qg Q q, the -adj ustable scroll L M m m N 'n n 0 P for guiding the fabricand tension tongue T, all constructed and arranged substantially asherein described and set forth.

4. The combination of spring-bar Z z 12 13 and adjustable edge-turnersl1 Yy, as stated.

5. lnasewing-machine binding attachment, the combination of edge-turnersto turn the edges of the binding, with a connected folder and back-guidefor the binding, said folder and back-guide being adapted to slidetoward and from the edge-turners for parallel adjustment, substantiallyas described.

In testimony of which invention I hereunto set my hand.
